Word Juggler was a word processor application by Quark, Inc. for the Apple IIe, IIc, and III computers. Until the release of AppleWorks, Word Juggler was the leading word processor on the IIe and IIc, beating out Apple Writer. The software was copy protected with a hardware dongle.
It was one of the first software titles to use ProDOS.
The software was well received and was considered easy to learn and master. The software also came with a dictionary/spell checker called Lexicheck which was also well received.
